| // For incremental linking tests, this file needs to be compiled with |
| // -fno-exceptions -fno-asynchronous-unwind-tables. |
| |
| // This tests references between files. This is file 1, and |
| // two_file_test_2.cc is file 2. We test in several different ways: |
| |
| // Files 1 and 2 linked together in executable. |
| // File 1 in executable, file 2 in shared library. |
| // File 1 in shared library, file 2 in executable. |
| // Files 1 and 2 linked together in shared library. |
| // Files 1 and 2 in different shared libraries. |
| |
| // We test the following cases. |
| |
| // 1 Code in file 1 calls code in file 2. |
| // 2 Code in file 1 refers to global data in file 2. |
| // 3 Code in file 1 referes to common symbol in file 2. |
| // 4 Code in file 1 refers to offset within global data in file 2. |
| // 5 Code in file 1 refers to offset within common symbol in file 2. |
| // 6 Data in file 1 refers to global data in file 2. |
| // 7 Data in file 1 refers to common symbol in file 2. |
| // 8 Data in file 1 refers to offset within global data in file 2. |
| // 9 Data in file 1 refers to offset within common symbol in file 2. |
| // 10 Data in file 1 refers to function in file 2. |
| // 11 Pass function pointer from file 1 to file 2. |
| // 12 Compare address of function for equality in both files. |
| // 13 Compare address of inline function for equality in both files. |
| // 14 Compare string constants in file 1 and file 2. |
| // 15 Compare wide string constants in file 1 and file 2. |
| // 16 Call a function directly after its address has been taken. |
| // 17 File 1 checks array of string constants defined in file 2. |
| // 18 File 1 checks string constants referenced in code in file 2. |
